Well it's not the cheap adapter. It's either interference at work or (my guess) not very clean/properly grounded power.
Going from my MacBook Pro through Dragonfly to the Magni to my HD650's isn't as impressive as the Magni/Modi P7 combo is. Not that it's a slouch, but the P7's I can only take 1/3 of the power of the Magni.
I have it turned up to 100% with the HD650. Turning it down to about 80% sounds better, but I've now decided I'd rather the Lyr than the Valhalla.
How much of the sound quality comes from the DAC? If I got a Lyr and kept using my Dragonfly as the output would it sound much better, or would I be better served to carry my Modi back and forth until I can get a Bifrost?
Now to find a powerstrip or something I can use at work to see if I can fix this. If not this is really of little use to me. I wanted it for work to power my P7's, not for home with my HD650.
Edit: I had my MacBook turned up to 100%, but iTunes was not. Now with it at 100%, I can only take about 50% of the Magni.
And it smokes my Onkyo home theater receiver headphone out.
So what is recommended on a $300-500 "Father's Day" ticket?
